PAINT COMPOSITION.

No Drawing.

T 0 all whom it may concern:

Be it known that I, ANDREW H. APPLE- GREEN, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented new and useful Im rovements in Paint Composition, of which t e following is a specification.

This invention has reference generally to improvements in thatclass of inventions known as coating and more particularly to an anticorrosive paint.

The invention has for its rincipal object to provide a coating for app ication on iron, wood and other surfaces for preventing rust, for serving as a filler, etc., thus serving to increase the durability of the surface coated and at the same time being such that it will not readily crack or peel off.

It is another object of the present invention to provide a coating of the above mentioned character wherein a substitute is employed for white lead thus materially reducing the cost of the coating.

The improved coating or paint may be said to consist of the following ingredients for making approximately 150 pounds:

Paper or wood pulp 50 lbs.

In mixing the above, the paper or wood pulp, lime, plaster Paris and lye are placed in the Water and allowed to soak or stand for 48 hours. The mass is now passed through a grinder until it becomes mushy. The soy bean oil is now placed in the mixture and thoroughly commingled and a ain the mass is placed through a grinder. now ready to be applied with a brush, at least for the first coat. It may be, however, applied with a sprayer provided more oil or water is added. For the second or final coat or for the first and only coat and one having a glossy finish, the asolene and rosin are thoroughly comming ed with the mass.

The functions and actions of the various ingredients may be stated'as follows:

Specification of Letters Patent. Patented Aug, 26, 1919 Application filed November 12, 1918. Serial No. 262,227.

The wood or paper pulp forms a part of the base or body and acts to absorb the moisture and the water for preventing a separa tion of the water from the mass and principally the oil. In addition the pulp acts as a filler for small holes in the iron work or other surface. The commercial advantage resides in the use of the same as a white lead substitute permitting of the manufacturing of a paint at a considerably reduced cost. The lime and lye also form a part of the base while the plaster Paris in addition to being a part of the base also serves as a pigment. The water and oil represent the vehicle or carrier for the base as does the gasolene while the latter also acts as a means for dissolving the rosin which in turn coacts with the gasolene in producing a glossy appearance or effect.

It is of course apparent that other coloring pigments may be used with the abo e mass, such as Venetian red, French yellow ocher dry powdered form, and china clay powder, etc.

It is believed in view of the foregoing description that a further description of the coating is entirely unnecessary. Likewise it is thought that the advantages of the same will be readily apparent.

Having thus fully described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A paint comprising a base including paper pulp and lime, a pigment, and a vehicle of water and oil, the base being first placed in the water and the oil being finally placed in the resultant mass.

2. The herein described process of mixing paint comprising thoroughly soaking amixture of wood pulp and lime in water, then grinding the mass, then commingling a vehicle of oil with the mixture, and then grinding the resultant mass.

3. The herein described process of mixing paint consisting in thoroughly soaking a mixture of wood pulp and lime in water, then grinding the mass, then commingling a vehicle of oil with the mixture, then again grinding the resultant mass, and then adding a quantity of rosin for producing a gloss and finally adding a solvent for the rosln.

In testimony whereof I afiix my signature.

ANDREW HUGO APPLEGREEN-
